Encephalitis literally means an inflammation of the brain, but it usually refers to brain inflammation caused by a virus. It may also be called “acute viral encephalitis or aseptic encephalitis”. Encephalitis is an infectious disease of the Central Nervous System characterized by pathologic changes in both the gray and white matter of the spinal cord and brain. It may be due to specific disease entity such as rabies or an arthropod-borne virus (arbovirus), or it may occur as a sequela of influenza, measles, German measles, chicken pox, herpes virus infection, small pox, vaccinia, or other diseases. The specific viruses involved may vary. Exposure can also occur through insect bites, food or drink, or skin contact.

Once the virus has entered the blood stream, it can localize the brain causing inflammation of brain cells and surrounding measures. White blood cells invade the brain tissue as they try to fight off the infection. The brain tissue swells (cerebral edema) and can cause destruction of nerve cells, bleeding with in the brain (intracerebral hemorrhage), and brain damage. This can cause neurologic deficits such as parplysis, speech changes, increased intracranial pressure, respiratory failure, seizure disorders, and shock can occur.

...﻿I. Intoduction
Encephalitis is inflammation of the brain. Encephalitis is an inflammatory process in the
brain parenchyma. It is associated with clinical evidence of brain dysfunction due to infective
(usually viral) or non-infective processes. The pattern of brain involvement depends on the
specific pathogen, the immunological state of the host, and a range of environmental factors. In
encephalitis the virus initially gains entry and...

...Encephalitis lethargica is a rare disease which is an atypical form of encephalitis that can cause symptoms that range from headaches to coma like states. Other potential symptoms include things such as double vision, high fevers, lethargy, and delayed physical and mental reactions. The treatment of the illness was the main focus of the movie awakenings and the book it was based upon. The cause of the illness even today still remains much of a mystery with...

...Encephalitis Lethargica
Encephalitis lethargica or von Economo disease is an atypical form of encephalitis, or also known as the “sleepy sickness”. Encephalitis lethargica was first discovered and described by neurologist Constantin von Economo in 1917. This disease is known to attack the brain, leaving some victims in a statute-like condition, speechless, and motionless. Encephalitis lethargica was largely spread around...

...Equine Encephalitis
Equine encephalitis is a virus us humans in south texas are exposed to through the abundance of a common vector, mosquitos. Mosquitos are known to be the most obligatory biological vector for transmitting these viruses. Of the three different types of “Group A” arboviruses, the eastern equine encephalitis and western equine encephalitis are the ones native to our area and can also cause febrile disease in humans and...

...Encephalitis
Specific Purpose Statement: At the end of my speech, my audience will be familiar with the disease Encephalitis; an inflammation of the brain usually caused by a viral infection.
Thesis statement: I will tell you about Encephalitis, by defining it, exploring its causes, discussing symptoms and diagnoses, and a few possible treatments.
Introduction:
I. Imagine for a second that you are 5 years old.

...was until then that we discovered that what Mr. Drake presented was a state of encephalitis which is the swelling of the brain dew to a virus. This virus can be caused by several reasons like West Nile, herpes, Arboviru (such as birds, pigs etc.) and also rabies as long as he got bit by something or touched some king of animal or travel out of the country he could have cached the virus. Once we knew that encephalitis was the case we processed with acyclovir by...

Abstract
For this paper I will be discussing a homeostatic imbalance of the nervous system called Encephalitis. Encephalitis is inflammation of the brain mostly caused by viral infections and some bacterial. (Mayo Clinic Staff, 2012) It occurs in approximately 0.5 per 100,000 individuals with it most commonly occurring in people...
